Patent number: 10146367Abstract: A synchronization method for a touch signal processing system is provided. The touch signal processing system includes a first and a second detecting unit. The method includes the following steps. First, the second detecting unit sends a sync start signal to the first detecting unit and then switches to an idle mode. After receiving the sync start signal, the first detecting unit sends a wake-up signal through a first hardware pin to the second detecting unit. The first detecting unit is then put on hold for a predetermined delay time. After receiving the wake-up signal through a second hardware pin, the second detecting unit switches to a working mode. The first detecting unit which has been put on hold for the predetermined delay time and the second detecting unit that is in the working mode respectively drive one or more analog-to-digital converters, so as to detect touch signals.Type: GrantFiled: December 21, 2016Date of Patent: December 4, 2018Assignees: IMAGINATION BROADWAY LTD., SALT INTERNATIONAL CORP.Inventor: Zong-Bin Liao
